TOOL FOR LAYING GOLD-LEAF.

SPECIFICATION forming part of Letters Patent No. 602,949, dated April 26, 1898.-

Application filed October 19, 1897.

To (all whmn it may concern;

Be it known that 1, JOHN C. F. KUNKLE, a citizen of the United States, formerly residing at Jersey Shore, in the county of Lycoming, and now a resident of Renovo, in the county of Clinton, in the State of Pennsylvania, have invented certain new and useful Improvements in Machines for Laying Gold-Leaf, of which the following is a specification.

My invention relates to the art of laying on surfaces, metallic leaf in strips, for the purpose of lettering or striping in the said leaf, and it is the object of my invention to provide a novel simple and efficient tool or apparatus by which such laying on of the leaf may be accomplished.

My invention relates particularly to a class of devices for laying gold-leaf in which a package and delivery roll and a receiving roll adapted for use in connection with a foil bearing coiled strip of paper, are both mounted in a supporting frame,the foil-bearing strip of paper hein gin the first instance coiled with its foil-provided face outward upon the package and delivery roll, which is so mounted in the frame that it may be presented directly to and rotated upon the surface to be decorated, and the strip being, in the operation of the machine, continuously wound upon the receiving roll as fast as it is unwound from the package and delivery roll and denuded of its foil,-and my invention comprehends in connection with a supporting frame of novel and useful character, the provision of a motor for automatically rotating the receiving roll to cause it to take up the paper as fast as the leaf is removed therefrom.

In the accompanying drawings I show, and herein I describe, a good form of a convenient embodiment of my invention, the particular subjectmatter claimed as novel being hereinafter definitely specified.

In the accompanying drawings,

Figure 1 is a view in side elevation of my improved machine for laying gold-leaf, sight being taken toward the front or face plate of the same.

Figure 2 is a view similar to Figure 1, with the front plate removed.

Figure 3 is a top plan view of the machine as shown in Figure 1.

Figure & is a vertical sectional elevation of Serial No- 655,685. (No model.)

the same, section being supposed upon the line 44 of Figure 1, and sight being taken in the direction of the arrows applied to said line.

Figure 5 is a view in side elevation of the outside face of the front plate of the frame.

Figure 6 is a similar view of the inside face of the back plate.

Figure 7 is a View in side elevation of the outside face of the intermediate plate.

Figure 8 is a View in perspective of a shaft upon which the receiving roll and its driven pinion or gear wheel are mounted.

Figure 9 is a view in perspective of the core of the receiving roll.

Similar letters of reference indicate corresponding parts.

The front plate A and back plate B are rigidly secured together in parallelism and at a desired distance apart, by a series of strutpins 0, and, together with said strut-pins, constitute the supporting frame of the device.

The plates A and B are practically counterparts of each other, except that the back plate Bis provided, for a purpose hereinafter explained, with a projecting guide prong b, which is omitted from the front plate.

Suitably j ournaled between these plates are, first, apackage and delivery roll D, consisting of an axiallyapertured core cl, and a roll or coil (1 of foil-provided paper mounted upon said core with its foil-provided face outside, and a receiving roll E, consisting of a core 6 upon which is adapted to be wound a roll or coil e of the foil-denuded paper which originally formed the foil-provided roll or coil (1.

The continuous strip of paper, therefore, which thus forms both the rolls (1 and e is, in the operation of the machine, constantly unwound from the core cl and wound upon the core e,being, as it is unwound, denuded of its metallic foil, which is deposited from oil the delivery roll upon the surface to be deco rated,-the device as an entirety being, as will be understood, taken in the hand of the operator, placed with the periphery of its package and delivery roll in contact with the surface to be decorated, and drawn or pushed across said surface, the package and delivery roll rotating upon said surface and unwinding as it travels.

In order that the receiving roll may oper ate to take up the denuded strip of paper as fast as it is unwound from the package and delivery roll, I provide a motive mechanism of any preferred character, by means of which the receiving roll is automatically rotated in the appropriate direction to take up said strip.

Many forms of such mechanism may be resorted to. I find it convenient to employ a clock-work mechanism of the following character:

F, Figure 53, is a motor shaft journaled in the frame plates A and B, and having a projecting end provided with a thumb head fby which said shaft may be manually rotated.

G, Figures 2 and 3, is a driving spur wheel, loosely journaled on said motor shaft, and adapted to be engaged with a driven pinion E which is mounted and fast on the shaft E of the receiving roll.

f is a ratchet wheel, shown in dotted lines in Figure 2, mounted on the motor shaft F, and affixed thereto,and F is a coil spring wound upon and connected at its inner end to said shaft F, and at its outer end secured to one of the strut-pins c or other fixed point of attachment to the carrying frame.

g is a pawl carried by the driving toothed spur wheel G, and held to engagement with the teeth of the ratchet wheel f by a spring 9 also carried by said spur wheel G.

If is a locking plate, mounted free for rocking movement on one of the strut-pins o, and having a lip 7L adapted to engage between the teeth of the driving spur wheel G, and a projecting thumb lug 7t, by which it may be conveniently manipulated and carried into or out of engagement with said spur wheel.

When a full package and delivery roll has been mounted in the machine, the thumb head fet' the motor shaft F is to be rotated to the left, with the result,tlie locking plate ll retaining the spur wheel G against rotation,-that the spiral spring upon said shaft will become tightly coiled.

The tendency of the wound spring then being to rotate the motor shaft F to the right, Figure 2, and, therefore, by reason of its ongagement through the ratchet wheel and pawl with the driving spur wheel, to occasion the rotation of said spur wheel to the right, it is manifest that as soon as the locking plate is thrown into the position shown in full lines in Figure 2, to release said spur wheel, it will rotate to the right in the manner referred to, and, through the driven pinion E will occasion the rotation, in the opposite direction, l. eing the appropriate direction to take up the paper strip,of the shaft E and of the receiving roll core on said shaft.

\Vhenever, therefore, the operator rolls the package and delivery roll along the surface to be decorated, he first throws the locking plate to release the spur wheel G, so that the roll it may be automatically rotated and the paper strip be automatically taken up upon it,and so soon as he completes this operation, he sets the locking plate to lock said wheel.

The axle E of the core e of the receiving roll is conveniently fora portion of its length squared to adapt it to be passed through a squared axle aperture e in said core.

The ends of the axle are, moreover, rounded to adapt them to be entered in corresponding apertures formed in a pair of supporting spring plates I I, mounted respectively upon the respective exteriors of the front and back plates, and which serve as a convenient device for removably securin g the receivin roll.

These spring plates I I are preferably formed of resilient metal, and, are provided with bearings for the axle E in their outwardly curved upper ends while their lower ends are respectively secured to the respective plates A and B,-with the result that their upper ends are free to be sprung slightly apart from each other to release the axle of the receiving roller when it is desired to remove said axle to supply it with a new core.

Notches 2' formed in the margins of the frame plates A B in the region covered by said supporting plates conveniently allow the receiving roller to be set well within the confines of the front and back plates.

The core (I of the package and receiving roll D is journaled partly on a pin I), Figure 4, which projects from the inner face of the back plate B, and enters one end of the axial aperture of the eoreof said roll, and partly on the advance end j of a set screw J threaded in the front plate A, which enters the other end of the axial aperture of said core.

The set screw J is provided in the vicinity of its advance end with a bearing plate j which bears against the side face of the core in the region surrounding its axial aperture and tends to confine said core against the back plate 13 with such slight pressure as may be desired to retard the unwinding of said package and delivery roll to offset excessive tension exerted by the motor.

In order to maintain the paper mounted on the package and delivery roll, and also on the receiving roll, against lateral displacement, I provide an intermediate plate K the shape of which is approximately the same as that of the back plate,and which conveniently embodies marginal recesses 7; to afford clearance for the strut-pins c, an aperture 7t" through which the motor shaft F extends, and an opening k through which the set screw J and its bearing plate extend.

This intermediate plate is mounted upon a series of set screws 7t, which extend from the front frame plate to the back plate, and, beyond said back plate, through which they extend in free, not threaded, relation, are equipped with nuts.

The central portions of these screws are in I 0 threaded engagement with suitable tubular threaded bosses 71: formed on said intermediate plate.

As will now be understood, the intermediate plate serves to confine between itself and the back plate the coils of paper mounted on the cores of the two rolls, and hence prevents said rolls of paper from slipping laterally from said cores.

lhe prong l) of the back plate,and the prong 7; of the intermediate plate extend diametrically of the package and delivery roll to near the point where said roll bears upon the surface to be decorated, and thus maintain the paper of said roll against lateral displacement in the region where it is most liable to be displaced.

By the adjustment of the screws referred to, the middle plate can, moreover, be set to allow of the use of rolls of different widths.

hen it is desired to remove the core of the package and delivery roll and to substitute a new one, the screws J and 7c are to be turned to the left to carry the intermediate plate and the bearing plate j sufficiently away from said core, to permit of said removal and substitution.

Having thus described my invention, I claim 1.
